- put the car on a lift;
- Disconnect the lead from the negative terminal of the battery;
- set the steering wheel to the straight ahead position and lock it;
- remove the front wheels;
- install clamps on all hoses coming from the reserve tank of the amplifier with working fluid to reduce fluid loss;
Attention! Never pinch high pressure lines.
- using a universal puller, press out the pins of the ball joints of the steering rods from the steering knuckles, having previously unscrewed the nuts of the pins;
- under the car, bend the cover that covers the steering shaft lower cardan joint assembly, and unscrew the eccentric bolt of the clamp of the universal joint cross;
- mark in an accessible way the relative position of the clamp and the shaft;
- disconnect the connector of the oxygen concentration sensor in the exhaust gases;
- remove a reception pipe of system of release of the fulfilled gases;
Pic. 6.4. Engine tie rod bolt
- remove the engine mount tie rod bolt (pic. 6.4) and tilt the power unit forward by inserting a wooden block between the engine and the motor shield;
- Disconnect the low and high pressure lines from the steering box (taking measures to collect the flowing working fluid) and unscrew the nut securing the pipe bracket. Plug the openings to prevent dirt from entering the system;
Attention! Do not remove the pipelines connecting the distributor to the power cylinder.
- unscrew the two nuts securing the heat shield of the right steering gear housing support;
- unscrew the four nuts and remove the bolts securing the steering gear to the rear of the subframe. Remove the clamps and mounting brackets on both sides of the steering mechanism;
- remove the steering mechanism from under the car;
- check the condition of the steering mechanism by visual inspection. Replace damaged and worn mechanism bearings as necessary. The rail should move freely, without jamming, in the body throughout its entire course; if there is such damage, replace the entire mechanism. Covers should not have cracks and ruptures, leakage of the working fluid is not allowed.
Installation is carried out in the reverse order of removal, observing the specified tightening torques.
Fill the power steering system with working fluid. Turn the wheels left and right (with the engine off), to disperse the working fluid throughout the system. Repeat the operation with the engine running, and then add fluid to the reservoir to the normal level. When installing a new steering gear, the ball joints of the tie rod ends are set to the position marked during removal. To do this, remove the toe-in bolt and tie rod end while holding the tie rod inner ball joint with a flat wrench. Mark the position of the tie-rod end ball joint or count the number of threads in engagement to pre-adjust the wheel alignment. Check and adjust wheel alignment if necessary.
